unpaper:用于扫描纸页的后处理工具

概述
unpaper是一种用于扫描纸张的后处理工具，尤其是对于已从先前创建的影印本进行扫描的书页而言。 主要目的是使转换为PDF后的扫描书页在屏幕上更具可读性。 此外，在执行光学字符识别（OCR）之前， unpaper可能有助于提高扫描页面的质量。
unpaper尝试通过消除在实际页面内容之外的区域（例如，双面书页扫描的左侧和右侧之间的深色区域）中扫描或复印时出现的深色边缘来清洁扫描的图像）。
该程序还尝试检测未对齐的页面居中和旋转，并通过将页面旋转到正确的角度来自动拉直页面。 此过程称为“偏斜校正”。
请注意，自动处理有时会失败。 手动控制排纸结果并根据输入要求调整参数设置始终是一个好主意。 也可以为每张纸单独禁用每个处理步骤。
